The time-travel drama is about a 21st century woman who gets transported back in time to the Goryeo Dynasty of Korea, where she becomes involved in the palace intrigue and court battles for political power, and love.

The entire cast is amazing and full of eye-candy, with IU playing our modern time heroine, Lee Jun Ki as the mysterious masked prince, and Kang Ha Neul as his main rival for the throne and her affections, forming the main love triangle. The other flower boy princes, played by Hong Jong Hyun, Nam Joo Hyuk, Baekhyun, Ji Soo, and Yoon Sun Woo, will also come into the fight for our heroine’s heart.
